Hello i have built a 112 280 remington and i am having misfire issues.The headspace is set corectly.I set the Brux barrel with Forester Go-& NO go gauges.I also had a gunsmith check headspace with his gauges before i had cal. engraved.I also had SSS T&T my action and install their trigger .I full length sized some cases and loaded 6 rounds 4 out of 6 did not fire.So i got some factory rounds and they all shoot fine.The factory rounds has a stiff bolt closing.So i got some once fired cases and barely touched the shoulders and it got better..I checked the firing pin protution and it was only 36 thousands I disasembled the bolt and adjusted the pin to around 52 thousands.I was shooting today not thinking about it and i had 2 cases (out of 20)to not fire.fireing pin hit primmer but no fire, looked like a light strike from firing pin.This thing shoots great but i cannot trust it does anyone have any ideas?Primers are CCI BR2 same primmers i use for my 25-06 without issues.Thanks Jamie
